CVE-2019-18660

Priority
Description
The Linux kernel before 5.4.1 on powerpc allows Information Exposure
because the Spectre-RSB mitigation is not in place for all applicable CPUs,
aka CID-39e72bf96f58. This is related to arch/powerpc/kernel/entry_64.S and
arch/powerpc/kernel/security.c.
Ubuntu-Description
Anthony Steinhauser discovered that the Linux kernel did not properly
perform Spectre_RSB mitigations to all processors for PowerPC architecture
systems in some situations. A local attacker could use this to expose
sensitive information.
